XVILLIAM HINGHLIFFE, OF NASHVILLE, TENNESSEE.

RAILWAY-HEAD, DRAWING-MACHINE, 84C.

@PBCIFICATION forming part. of Letters Patent No. 318,900, dated May 26, 1885.

Application died April 2, 1884. (No model To all whom, it may concern.-

Be it known that I, \VILLIA M HINCHLIFFE, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented a new and useful Indicator for RailwayHeads and Drawing- Machines, of which the following is a specification, reference being bad to the accompanying drawings.

This invention relates to railway-heads and drawing-machines; and it consists in certain new and useful devices to be employedin connection with the calender-rolls thereof to in dicate the variations in the sliver therethrough, all as will be hereinafter fully described, and particularly pointed out in the claims.

Figure 1 is a view in perspective ofthe up per portion of a railway-head with my improved indicator attached thereto. Fig. 2 is an end elevation of the same. Fig. 3 is a vertical sectional view showing the interior mechanism of the indicator. Fig. eiisadetail view of the indicatorlever. Fig. 5 is a detail view of the indicator. Fig. 6 is a face view of the indicator, and Fig. 7 is a detailed side elevation showing a modified form of the lever.

Referring by letter to the accompanying drawings, a designates a railwayhead, and c and dare the calender-rollers of the machine, which are journaled in the bearing-arms at, having the journal-boxes a in the usual manner, as shown in Fig. 1.

The lever b is connected at one end to the top roller, 0, by a finger, 0, which projects from said roller, and the other end is connected to the sector (I of the indicator.

The calender-rollers of the machine deliver the cotton-sliver, and as the cotton varies in weight or bulk the top roller, 0, rises and falls. The lever b, which is attached to the roller by the finger o, is carried with the roller and operates the indicator-pointer by its connection with the sector (I. f is a carrier orintermediate toothed pinion, and h is also a pinion, to the axle of which is attached the pointer t. Between the flat spring and the pinion h is a thin leather washer, i,to prevent the pointer t from being vibrated by the jar of the machine when in operation.

X designates a plate, in which are journaled pinions f and it, and also sector d. This plate may, however, be omitted and the pinionsand segment journaled in the case h.

k designates a bracket, which supports the lever b, and is bolted to the machine, as shown.

The bracket k is made in two sections, k and L The section is slotted at its upturned end, as at 76, and to this upturned end is secured the section It" by means of a bolt 70 which passes through the section k and through the slot. A set-screw, k, passes vertically through a projection or lug that is formed on the section k and bears against the under side of the section It. By this construction the section 70 is adapted to be adjusted vertically, as will be very readily understood.

The leverbis recessed at one end, as at b, and in this recess is inserted the part or, which has an open slot cut in its outer end for the reception of the finger 0 and ashoulder, m, formed on its inner 'end on its upper side. A pin, 10, passes through the part b and bears upon the shoulder m, and in a recess which is formed in the under side of the part b is secured a spring, a, by means of pins a, which spring bears against the under side of the part m, at the inner end thereof, as shown. The lever bis pivoted in between cars at the upper end of the section 7.: of the bracket by means of pointed screws g, which pass through the ears, through the portion 1), and enter the portion m. This construction forms a knuckle-joint in the le ver, the object of which is to enable the lever to yield in case of accident by cotton winding on the calender-rollers and avoid injury to the indicator.

The indicat-ordial is provided with two pointers, one of which, if, is attached to the pinion-shaft. The other,whieh1 term a deadpointer, s, is formed of a circular piece of brass or steel wire, which is placedin a circular groove, 2, that is made in the face of the dial. A loop, 12, is bent in the wire opposite to the point r, and through this loop passes the pointer t, which vibrates between the sides of said loop when the work is running evenly through the machine.

Trifling variations in the thickness of the sliver will cause the pointert to vibrate between the sides of the loop without affecting the dead-pointer; but in the event of a considerable deviation in the sliver from the requisite thickness the pointer 25 will be moved far enoughtocause itto strike against one side of the loop of the dead-pointer and cause the dead-pointer to move and indicate the fact to the operator.

This indicator is simple in construction, positive and accurate in its action, and is not liable to get out of order.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The combination, with the calender-rollers of a railway-head or drawing-machine, of the pivoted lever connected to the upper of said rollers, an indicator having a dial-face and a pivoted pointer, gears for connecting the free end of thelever to the pivoted pointer, and a dead-pointer in the dial-face, having a loop through which the pivoted pointer passes, for the purpose set forth substantially as described.

2. The combination of the dial-plate, the pinion h, the pointer 15, fast therewith, the pivoted lever, the roller journaled in one end thereof, a gear connecting the free end of the pivoted lever with the pinion h, and the deadpointer having a loop through which the pivoted pointer extends, for the purpose set forth, substantially as described.

' In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

WILLIAM HINGHLIFFE.
